TELEPHONE ATTACHMENT.

Specification of Letters Patent.

Patented Feb. 1, 1921.

Application filed July 10, 1919. Serial No. 309,930.

To all fw hom 'it may concern Be it known that I, HARRISON D. STER- nien, a resident of Pittsburgh in the county lll of Allegheny and State of zPennsylvania, have invented a new and useful Improvement in Telephone Attachments, of which the following is a specification.

This invention relates to telephone desk sets. lts object is to provide a transmitting and receiving set` in which the receiver is supported from the desk set in such position as to transmit t-he sound waves to the users ear, thereby leaving both hands of the user i'ree so that he can make memoranda, readily consult records, etc., while carrying on the conversation. j j

The invention can be embodied in a specially constructed desk set, but is also adaptable as an attachment which can be secured to standard desk sets, and which when so attached Twill securely hold thereceiver and is so constructed that its center of gravity is fairly close to the center'of gravity of` the set itself so that the balance of the latter is not destroyed.

In the accompanying drawings Fi ure 1 isa vertical sectional. view showing t e inn `vention applied as an attachment to a standard telephone desk set; Fig. 2 is a rear elevation` of the same; Fig. `3 is a horizontal section through the `stand immediately below the top collar thereon, and Fig. 4 is a fragmentary view partly in section showing one manner of adapting the invention as a permanent part of the telephone set. j

ln the drawings 1 indicates the stand or support oi a Aform of desk telephone set in extensive use, the same having hinged to its upper end the usual microphone transmitter and mouth piece `2. 3 indicates the usual hook for suspending the telephone receiver. The means illustrated for securing the in` vention as an attachment to a telephone stand, as shown in Figs. 1, 2 and 3, comprises a pair of bands 5 and 6A fastened around the stand 1, one above and the other below the usual collar 7 formed on said stand. The bands have their ends connected by suitable clamping means, such as compression bolts 8 passing through radial ears on the ends of said bands. arious other arrangements for securing the attachment to the stand will readily suggest themselves.

The band 5, at the rear of the stand 1, has formed thereon or secured thereto a disk or friction member 10. Another disk or friction member 11 is secured to the member 10 by any suitable pivoting means, such as the bolt`12, which serves also to adjust the frictional contact between the members 10 and 11, such as by means of the nut 13 on its end and `the spring 14: interposed between said nut and the member 11. Secured to or formed integral with the member 11 is a horn 15 of such shape that when it is swung j sidewise to an inclined position its open end 16 will be in position to be contacted by the ear of the person who is speaking into the mouth piece 2. YVithin this horn is located the receiver 17 which may be (and Jfor permanent constructions preferably will be) constructed especially for that purpose, but which, for attachments to existlng sets will be the standard telephone receiver, and is so shown :in F igs.` 1, 2 and 3. This is inserted through an opening 18 in the back of the horn 15` and its upper end is held incontact withan internal shoulder 19 in the horn by means of a spring 2O in the base of the horn and bearing a ainst the outer end of said re ceiver. 21 in ica-tes the usual cord leading tothe receiver. j

Normally, that `is when not `in use, the horn will sta-nd in Vvertical position, as shown in Fig. 2, projectin up behind and over the transmitter 2. used, it isswung to one side or the other, until it is -in such position that its open end 16 can be contacted by the ear of the' user. It will remain in either -position by reason of the rictional Contact between the members 10' and 11.` i

In order that the movementof the horn may also serve to make and break the circuit, as is usual, the memberll is provided with a projection 22 which is arranged to contactwith a lever 23 whichis pivoted at 24 to the""band 6, and whose free end engages the telephone hook 3 at the point 25. The projection 22 is so located that when the horn 15 is `in vertical position it presses downwardly on the lever 23,`thus causing said lever to depress the telephone hook 3 to break the circuit, exactly as though the receiver 17 were hung on said hook; but when the horn 15 is swung to one side the projection22 moves out of contact with the lever 23 thus permitting the telephone hook 3 to rise in the same manner as it does when the usual suspended receiver is removed therefrom.

The attachment described is of simple ien it is to be Fig.' l shows; one manner in which the1 invention can be applied to aV telephone set as apermanent part thereof. As here shown they disk l0a is Jformed integral with the upymeans as are shown in Fig. 1.

per portion' of the telephone stand, whileithe disk 11a is-pivoted thereto and held in frictionalv Aengagement therewith by the same The mem- Y n. berilla vwill carry the horn l5, which may be horn.

oi the shape shown 'in Fig. l or otherwise formeldsoy that when moved to one side its open end will bein position to be contacted bythe ear oftheffuser.V VVn this case the .ree ee'ivercan and preferably will be specially constructed .and permanently built in the vWith such permanently built in receiver the usual vhook 3 can obviously be rmodified andfdierently located, and, as

shown, merelyis a short pivoted arm 3a projectingffromthe rearv of the standfl, in a position to be directly contacted by the projection'22 on member 11a. Various other arrangements fory embodying the invention as aA permanent part of the telephone set will obviously occur to those skilled in the art.

Various modiiications in the construction and arrangement of parts can obviously be made vwithout departing from the invention as hereinafter' claimed.. y

- I claim:

. l. In'atelephone, in combination, a stand or support,a transmitter carried thereby, a

hornpivotally connected to said Vstand to the rear o-'saidY transmitter and arranged toA normally extend over said transmitter and to be swung to one side to bring its open endinto position to be contacted by the ear of a personspeaking into said transmitter, and a receiver associated with said horn.

YY 2., vvIna telephone, in combination, a stand or support, a transmitter carried thereby, a

horn pivotally connected to said stand to the rear of said transmitter and arranged to normally extend over said transmitter and to be swung to one side to bring its open end into position to be contacted by the ear of a person speaking into said transmitter, a receiver associated with said horn, a cut out switch, and a projection on said horn arranged when the horn is in vertical position to depress said cut out switch and when the horn is in horizontal position to release said cut out switch.

3. A telephone attachment comprising a support arranged to be attached to a telephone transmitter set, a horn arranged to contain and hold the receiver, a pivotal connection between the horn and the support arranged to permit the horn to move from vertical inactive position to one side, and connections between the horn and the usual receiver cut out hook, said connection including a cam so arranged that when the horn is in vertical position the eut out hook is depressed and when the horn is swung to either side said cut out hook is permitted to rise.

Ll. A telephone attachment comprising a support arranged to be secured to a telephone transmitter set, a horn formed to contain and hold the receiver, a pivotal connection between the horn and the support, a. lever pivoted to the support and arranged to contact the cut out hook, and a projection movable with the horn and arranged when the horn is in vertical position to depress said lever and when the horn is swung to either side to release said lever and permit the cut out hook to rise.

A telephone attachment comprising a support on a telephone transmitter set, a

horn pivoted to said support to the rear of' the transmitter, the free end of said horn curving forwardly, said horn being provided with an internal shoulder and with an opening through its wall permitting the receiver to be inserted therethrough, and means for holding the receiver end against the internal shoulder of the horn.

In testimony whereof I have hereunto set my hand.
